Nuclear Weapons And The Development Of Nuclear Warfare Essay -- Nuclea

Nuclear weapons are the most powerful and destructive technology ever created. From the first notion that nuclear technology could be harnessed to create a bomb, massive amounts of time and energy (as well as government funding) have been invested in further increasing the destructive yield of nuclear weapons. The process of development was carried out independently by governments worldwide. Despite the segregation of groups of scientists and secrecy surrounding their discoveries, design strategies and problems remained basically the same in all development projects with similar solutions being realized more or less concurrently. The first and most basic fission bomb quickly evolved to produce higher and higher yields. Through discoveries and modifications, nuclear technology evolved to eventually produce fission-fusion weapons, which are what compose most of the nuclear arsenal today. Further development, ironic as it may seem, is highly unnecessary and unlikely (except, perhaps, t o increase efficiency) due to the ridiculous power wielded in every modern thermonuclear weapon. The popular modern threat of nuclear weapons is the possibility of terrorist groups acquiring the materials to produce bombs. 'Lo-tech' nuclear weapons are feasible and would seem highly desirable for such groups to possess. The home enthusiast might even flirt with the idea of creating his or her own nuclear arsenal. Assuming one could obtain 10-20kg of highly enriched fissionable material, this may not be such a romantic idea after all. There are a number of things anyone must know about nuclear weapons, however, before declaring themselves a nuclear power. Fission Weapons (Atomic Bombs) Fission weapons, or "Atomic Bombs", are based on nuclear fission. Nuclear fission occurs when the nuclei of certain isotopes of heavy elements (such as uranium or plutonium) capture neutrons. The result is that the nuclei become unstable and break apart into two smaller nuclei. This process converts some of the mass into energy and releases varying numbers of neutrons that go on to collide with other nuclei causing them to break apart and so on and so on. In nature this process is irrelevant due to the low natural occurrence and densities of radioactive isotopes. During weapons construction, however, isotopes are refined and concentrated to ultra-pure forms so that fission can occur at the ... ...can be added on. The fusion reaction can go on to start another fusion reaction and so on with unlimited yield. The most powerful weapon ever conceived was of a similar design. The Russian "Tsar Bomba" (King of Bombs) was a fission-fusion-fusion weapon with an additional fission jacket surrounding the third stage that would have produced a yield of at least 100 megatons if it were ever exploded. Without the additional fission jacket it still produced the largest nuclear explosion ever at 50 megatons. Works Cited Brown, Richard K.

Effects of overpopulation Essay

Even thought the world is witnessing a sustainable improvement in all fields such as science and technology, it is still facing several problems that keep blocking it from improvement. One such problem is overpopulation that affects our life in many ways. Overpopulation generates three major effects: economy decline, environment downfall, and educational system decline. The first major effect of overpopulation is economy decline. When a country is overpopulated, it barely can support and provide people with necessary food to survive, so it will have no surplus to export. Not only this, but the worst thing is when a country is not able to feed its own people, then the only solution is to take debts from other countries. This puts the country in a critical situation from the economic perspective. Moreover, when the country is overpopulated, there is a high rate of unemployment because the government cannot afford job opportunities for the whole population, and also there will be no for eign investment because wherever there is overpopulation, there is an economic decline. One way or another, this situation will lead to crimes and other kind of problems. Environment downfall is the second main effect of overpopulation. First, when there is overpopulation, people need more space where to live, and that means less of green space, less of forests, and less of farmlands. things that are necessary for surviving. Second, how says overpopulation says pollution with all its different types; as a result, the air, the water, and all the earth’s resources start being torn down. Finally, a high rate of population implies an abusive usage of natural resources; consequently, within a short period of time, we will end up being in a world empty of natural resources, especially the non-renewable ones. The third and the last main effect of overpopulation is educational system decline. The higher the population of a country, the more teachers are needed in schools, and this leads directly to overcrowded schools since the government cannot afford the cost of paying additional teachers, and building new schools with larger capacity. This will affect in a very negative way student’s way of learning and attitude; for instance, when they see that the conditions are discouraging and not motivating for studying, either they drop out of school or they get involved in some morale deviation like drug  usage. Above are the three main effects of overpopulation and their characteristics. It is an issue that concerns everybody, so people should start to think about it seriously and take the necessary measures to reduce or at least stop this phenomenon that is making our life harder from increasing.

Ego-Centricity and Socio-Centricity

The Different Windows of Life We all see the world In different perspectives and that's how we, as humans, handle this Journey called life. Two of the many different views of life are ego- eccentricity and solo-centrally, they may seem new to you but actually they're already spread out In the minds of different Individuals. As seen In the structure of the two words, egocentricity and egocentricity, they are obviously two different words not only in structure but also in meaning.Let me elaborate on their difference in meaning based on their structure. Egocentricity comes from the Latin word â€Å"ego† meaning â€Å"l† and â€Å"centrists† meaning â€Å"centered upon†. From their etymology we can infer that the word meaner centered upon oneself. Egocentricity is having opinions or views in life which highlight oneself or give importance to the decisions of an individual. Ego centrists believe that they are the most Important living things on the earth more t han any plant or animal and their view on life Is mostly Influenced by oneself only.They believe that life Is colluded by Individuals and not by any social group or plant/animal. On the other hand Socio-eccentricity coming from the Latin word â€Å"socio† meaning companion and â€Å"centrists† meaning â€Å"centered upon† meaner having views or opinions based on one's membership in a social organization. Socio-eccentricity is having views that one is dominant because of his/her participation in any social organization or structure. Socio-centrists often associate themselves within their group and not as an individual not unlike the former.They also believe that life Is McCollum by societal groups and not Just by any individual. They believe that 2 heads are indeed better than one. No matter what flews/pollens you Imbibe wealth yourself, believe that the world Is McCollum by what we do and not what we think of ourselves or any human being. We can only solve the p roblems of the people if we do some action about it. We can never solve anything based only on our views. We can only bring an end to these if we do our part as human beings here on earth.

Free Essays on 7 Habits Of Highly Effective People

THE 7 HABITS OF HIGHLY EFFECTIVE PEOPLE The 7 Habits of Highly Effective People was written by Stephen R. Covey in 1989. This book has been on the National Best Seller list for over 200 weeks. Many people have attended Covey’s seminars on the subject. Many companies have required top executives to read this book including AT & T, Dow Chemical, Ford, Deloitte and Touche, Marriott, Xerox and Ritz Carlton Hotels. This book proposes that there are seven habits that can be learned to improve one’s personal and interpersonal effectiveness. Covey describes a habit as â€Å"the intersection of knowledge, skill and desire.† Knowledge would represent the â€Å"what to do†, skill the â€Å"how to do†, and desire the â€Å"want to do†. In order to create a habit in our lives, we must have all three. Habits 1, 2, and 3 relate to Private Victory with habit 4, 5, and 6 relating to Public Victories and Habit 7 being involved with Renewal. Habit one is to be proactive. This habit says that as human beings we are responsible for our own lives. Our behavior is a function of our decisions, not our conditions. We create our own destiny. The proactive person acts rather than waiting to be acted upon. According to Covey, part of increasing our self-awareness is understanding our Circle of Concern, that is, our range of concern with which we have mental or emotional involvement. A Circle of Influence resides inside the Circle of Concern reflecting those things over which we have control. Habit two is to begin with the end in mind. If we paint a visual image of what we want our life to be then we actually provide a frame of reference within which all our behaviors can be examined. We must understand where we are going. We should develop a personal mission statement. It will provide the basic direction of our lives. This statement will force us to give thought to our values and what we want to accomplish in life.

The 5 Best SAT Apps How to Use Them Effectively

The 5 Best SAT Apps How to Use Them Effectively SAT / ACT Prep Online Guides and Tips You might use apps to take photos of your food and put dog filters on your face, but did you know you can also use apps to prepare for the SAT? It's true! There are a number of apps designed to increase your familiarity with the SAT and get you closer to reaching your goal score. In this article, I'll let you know how you can use apps in your SAT preparation, and I'll name five of the best free SAT prep apps currently available. SAT Apps: An Overview As mobile apps have become more popular, the College Board, SAT prep companies, educational app companies, and individuals have created their own apps to help students prepare for the SAT. Those who have created the apps are trying to capitalize on the popularity of mobile appsand want to make SAT prep material more accessible for students. If you have an SAT prep app on your phone or tablet, you can conveniently study for the SAT wherever you’re at,whether you’re at home, school, or a boring family function.Also, studying on an app is more enjoyable and interactive for some students than is using a traditional SAT prep book. While most SAT prep apps are free,some do cost money in order to use them. Why SAT Prep Apps Are Not Enough SAT apps can be a good study tool, but you probably won’t be able to solely rely on them to hit your target score. If you want help doing that, check out our guides onhow to get a perfect score on the SAT and the best ways to study for the SAT. So why aren't SAT apps enough? Here are some key reasons to be aware of. For one, most SAT apps don't have adequate practice questions.Either there are too few of them or they're not representative of the questions you'll get on the actual SAT. As a result, you'll likely need more real SAT questions or more realistic practice questions to be able to sufficiently drill your knowledge and improve your content weaknesses. Secondly,apps don’t always teach you helpful SAT test-taking strategies.Most SAT apps don’t cover test-taking strategies in detail, such as how to read the SAT Reading and Writing passages. Finally, mostSAT apps aren’t customized to your skill level.To improve your score, you need to focus on improving your personal weaknesses. For example, you might want to get better at time management on the Reading section, or you might need lots of help with linear equations. Generally, SAT prep apps aren’t effective at determining where you’re weak and aren't designed to help you zero in on the areas in which you need to improve your skills most. Sorry kid, you're gonna need more than an app to get a 1600. What Makes a Good SAT App? There are specific qualities you should look for in an SAT practice app. #1: Tons of Realistic Practice Questions The best SAT apps will offer hundreds of practice questions for you to hone your skills. These questions should use the same format as questions that appear on the SAT and should be roughly as difficult as those on official SAT practice tests. Moreover, solid questions will provide you with thorough answer explanationsso you’re able to understand how to correctly approach and answer them. #2: Good User Experience SAT apps should be easy to navigate and use. On some SAT prep apps, the text is hard to read or the setup of the app makes it difficult to identify the functions and navigate among them. #3: Thorough Content Instruction A good SAT prep app will clearly teach you the content you need to know in order to excel on the SAT.After doing a lesson or reading an answer explanation, you should have no lingering confusion about the topic you're studying. A quality SAT app will break down the topic and thoroughly explain it. You should be able to start with limited knowledge on a topic and then, after using the app, understand it well enough to correctly answer related SAT questions. A bad app will provide only brief instruction, meaning you'll continue to be uncomfortable with a content area you struggled with. If you have any unanswered questions about a topic, you'll need more content instruction. Apps aren't always the best teachers. #4: Questions and Lessons Are Divided by Specific Topics A good SAT app will divide practice questions and content instruction by more specific topics than just Reading, Writing, and Math. If you know the topics on which you need extra help, you should know exactly where to go. If you need more help with comma rules, for example, you should be able to easily find instruction or practice questions to help you study that specific content area.

Designed and led by PrepScholar SAT experts, these live video events are a great resource for students and parents looking to learn more about the SAT and SAT prep. Click on the button below to register for one of our livestreams today! The 5 Best SAT Apps If you want to use SAT practice apps in your studying, here are five that can provide some benefit to you. All are free of charge! #1: Daily Practice for the New SAT iPhone | Android This isthe College Board’s official SAT prep app.Every day the app offers a new practice question, which can cover any topic. This feature might not help you if it’s on a topic you already know. Since previous questions of the day are archived, though, you can access these instead. These are organized by section and can be sorted by difficulty level or even the date they were posted. The official SAT app also has a function through which you can scan an official SAT practice test you've taken and get it corrected. Unfortunately, many app users have complained that the scanning function doesn't work well, so be aware of this potential issue before using the app. This app is overall solid because it offersCollege Board-approved questions and explanations. However, it doesn’t have thorough content instruction, and the number of questions is limited. #2: Ready4 SAT iPhone | Android This app is definitely one of the best SAT prep apps.Itoffers the following features: Ample content instruction A mock SAT with up to 100 questions Complete answer explanations to questions 60 SAT lessons Hundreds of virtual flashcards 1,000+ realistic practice questions Initially, you take a short diagnostic test of 10 questions so that the app cancustomize a course of instruction for you. However, because there aren’t many questions in this test, the app might not be able to accurately determine your current SAT skill level. Though a great SAT prep app, it's not perfect. First,the content instruction it provides is pretty brief, so it might not be enough if you’re really struggling with a particular topic. The user experience isn't ideal, either. For Reading and Writing, passages and questions are on different screens, and it was a little difficult for me to find the underlined portions of the passages for the Writing questions. Additionally, the app isn't maintained regularly. The last update to the iOS version came in September 2017, which means that the content might be out of date. Additionally, old apps can be unstable and crash often, so your mileage may vary there, too. Lastly, the entire app isn't actually free. While you can access some of its features without having to pay, you'll need to fork out $19.99 for a premium account if you want the full experience. #3: Khan Academy iPhone | Android The Khan Academy SAT prep app offers a portion of the Khan Academy SAT prep website. (The Khan Academy is a partner of the College Board.) With this app, you get quality video instruction that walks you through a number of practice problems related to SAT topics. I enjoyed these videos, and I believe watching them is a good way to improve your content knowledge and ability to tackle SAT questions. Unfortunately, the app doesn't offer actual SAT practice questions for you to do. That's because the Khan Academy app isn't just for SAT prep...it gives users access to all of Khan Academy's lessons. All in all, you might as well just use the website so you can have access to the practice questions and everything else Khan Academyhas to offer. #4: SAT Exam Prep Practice Test / SAT Test Prep Practice Q A iPhone |Android The free version of this SAT app offers 300 practice questions, but if you pay $0.99-$1.00, you'll get 471 total questions, a mock SAT, and access to so-called â€Å"SAT Genius experts.† On the positive side, this app has many realistic Math practice questions and perhaps the best user experience of all apps on this list. Negatively, however, the explanations to the questions aren’t great, and there’s no real content or strategy instruction. Like other SAT apps, the app isn't updated regularly, either. (The last update was in December 2017, which means the app might be out of date and/or unstable.)Also, avoid the Critical Reading, Language Vocab, and Word Knowledge questions altogether- these don't use passages and are nothing like actual Reading and Writing questions on the SAT. #5: SAT: Practice, Prep, and Flashcards iPhone | Android This app, created by Varsity Tutors, offers in-depth study materials for the SAT's Math, Critical Reading, and Writing sections. The two biggest perks of this app are its user interface and its flexibility. First, the app is well designed and easy to use. You can pick subjects, practice materials, and even a flashcard deck quickly and easily from the navigation menu. Honestly, the app is justpretty. In terms of flexibility, the app gives you many different ways to study. Not only does it offer diagnostic and practice tests, you can also study by concept, choose a pre-made flashcard deck, or just answer the app's Question of the Day.It's also easy to focus on your weakest categories because the app breaks its content down by test section and subject areas. Lastly, the SAT: Practice, Prep, and Flashcards app lets you time your practice so you can see how much time you're spending answering different types of questions. On the negative side, this app- like so many others in this category!- isn't updated regularly. While it's stable and usable for now, it's not clear whether that will be the case in the future. Additionally, there's a chance the questions and information are out of date, too. The SAT is constantly updating its question types, which means you need to study current materials to make sure you're ready for the test. How to Use SAT Apps in Your Studying: 4 Tips As previously mentioned, SAT apps can be a good resource, but you shouldn’t solely rely on them for your SAT prep.Here are some ways you should use SAT apps in your study sessions. #1: For Additional Practice Questions In your SAT studying, start withofficial SAT practice tests. The questions on these tests most closely resemble real SAT questions, and the College Board provides explanations for all of them. Use one test to get your baseline score and to figure out how many points you'll need to get in order to hit your goal score by test day. Next, start to gather other crucial SAT resources: buy prep books, hire a tutor, and/or sign up for an SAT prep course. Once you've gathered your primary materials, use SAT apps as supplementary resources. With apps, you can do additional practice questions (once you've used up those in your books and tests) and can continue to drill your basic knowledge. I’d start with the College Board app since it's the only app to offer official SAT questions. #2: To Improve Your Weaknesses If you know the types of SAT questions you struggle with, you can use apps to do more questions related to those topics or to get more focused content instruction. For content instruction, Khan Academyand the SAT: Practice, Prep, and Flashcards app are pretty good. I’d also use the apps that organize questions by specific topics. Be sure to focus on the topics with which you need the most help. #3: To Change Up Your Study Routine If you’re always studying with the same SAT book or website, you can use an SAT app to alter your normal routine. Changing your routine can energize you and give you additional motivation to study. Just make sure you’re using the apps in a way that will be most beneficial to you or you'll end up wasting your time. For example, don’t just drillHeart of Algebraquestions if you’re already getting all those questions right in your prep. #4: To Take Mock Tests A few of the SAT apps offer timed mock tests and diagnostic tests. You can use these apps to simulate the test-taking experience. However, unlike the actual SAT, you'll be by yourself and you'll be doing the test on an app, so it won't be an exact simulation. That said,you can build up your test endurance and check to see how you’re doing with time management under pressure.You can also use these tests as diagnostics to help determine the types of SAT questions with which you’re still struggling. Best SAT Apps: Takeaways and Recommendations SAT apps can help you in your test prep as long as you ultimatelyuse them in conjunction with other high-quality resources, such as SAT prep books, a tutor, or a prep course. SAT practice apps work best once you already have a solid foundation. In other words, you should be familiar with all the content on the SATand be aware of your current weaknesses. Furthermore, keep in mind that you’ll have to learn test-taking strategies elsewhere. If you can afford to pay for a resource, our fully customizable SAT prep program improves your weaknesses,teaches helpful strategies, and provides plenty of high-quality practice questions.

NCLEX-RN is a national multiple choice exam overseen and administered by the National Council of State Boards of Nursing. It was first introduced in 1982 as a paper-and-pen two-day exam to a computer-adaptive test in 1994 which is also the present test form. TM was introduced in 1997 there are not many similar studies therefore. According to Rubino (1998) there exists a correlation between NCLEX success and NET scores. Among others, according to the Alexander and Brophy (1997) study the firmest predictors of NCLEX success were SAT verbal scores, nursing grade point average (GPA) and National League for Nursing (NLN) Comprehensive Achievement Test scores. Another study by Barkley, Rhodes and DuFur (1998) detect a bond between on standardized test scores and NCLEX, while Beeson and Kissling (2001), Briscoe and Anema (19999), Endres (1997), Swenty (1998), Wescott (1997) employed academic and non-academic variables for their stidoes: the Mosby Assess Test, NLN Achievement Tests, RN Entr ance Examination and ACT. These former content a high GPA is a predictor of success in nursing courses, and above the average scores on standardized tests were predictors of success on the NCLEX exam. Finally the study by Beeman and Waterhouse (2001) suggest that the results of NCLEX could be accurately via available student data. Study Framework, Research Objective and Study Design A drop in NCLEX-RN scores in 1997 led to exploration of failures rates and finding ways to overcome these. Defining predictors of NCLEX-RN such are the Nurse Entrance Test (NET) and Pre-RN exams of the Educational Resources, Inc. (ERI) and part of the Total Testing (TM) package. Total Testing is a monitoring technique held during the course of study and aims to increase NCLEX success evaluating student diverse performance under diverse conditions. The study at hand utilized for the purpose of the paper is a correlational comparative study utilizing the formerly mentioned NET and Pre-RN exams to answers the following questions: Is Pre-RN is the proper tool for NCLEX-RN success rate forecast Is NET is the proper tool for entrance to a nursing school program Are both Pre-RN and NET are predictors to successful performance on the NCLEX-RN exam Variables Analysis was performed using descriptive statistics with inferential statistics employing strength of relations between the measured variables, difference between groups' means, and confidence interval in a two-tailed test (Sayles, 2003). Demographic variables are used as independent along with average point and other marks, grade point average, ACT and additional test scores, taken courses and work experience. Sample, Population and Setting The studied sampled included the senior 83 students of an Associate in Nursing Degree Program (AND) and was held in 2001. (Sayles, 2003) with 78 students graduating and 68 of them taking the test for the first time. Data were obtained by university records and records form the nursing college and were divided in four categories of demographic data, applications to nursing courses, NET and Pre-RN data and the NCLEX results. The analysis and correlation
